Hi
I have upgraded a machine running FreeBSD 3.0-R to 4.6-S. When I try to
mount /usr (the last partition in the first and only slice on the disk),
I get the following:
ad0s1: slice extends beyond end of disk: truncating from 12692736 to
12692295 sectors
ad0: raw partition size != slice size
ad0: start 0, end 12692294, size 12692295
ad0c: start 0, end 12692735, size 12692736
ad0: truncating raw partition
ad0: rejecting partition in BSD label: it isn't entirely within the slice
ad0: start 0, end 12692294, size 12692295
ad0f: start 408256, end 12692735, size 12284480

I can take this disk to another 3.0-R machine and successfully mount the
/usr file system. I largely followed the steps in src/UPDATING,
including building a 4.6 mknod and disklabel on the 3.0 machine and
updated the /dev slices with
sh MAKEDEV ad0
sh MAKEDEV ad0s1
I also installed new boot blocks with
disklabel -B -b /boot/boot1 -s /boot/boot2 /dev/wd0s1
Why does the kernel think that the sectors/unit on the in-core copy of
the disklabel is incorrect?
I'm trying to "mount /dev/ad0s1f /mnt"
The disk copy and the kernel copy are shown below, as is a 4.6 dmesg
